Coiled tubing

Coiled tubing has a key role to play, with strong arguments for itself: It is used throughout the life of a well, from exploration to abandonment, and its flexibility of use, combined with recent technology developments in pipe materials, real-time downhole telemetry, and specialized downhole tools—just to name a few—opens avenues to perform in a rigless manner many o…
This study illustrates how a combination of a straddle-packer system and a downhole real-time telemetry successfully stimulated up to 38 stages while maintaining packer-seal integrity and downhole pressure.
The authors of this paper describe an underbalanced coiled-tubing drilling campaign in the operator’s onshore fields using a closed-loop system design.
